STL is a file format native to the stereolithography CAD software created by 3D Systems. STL ( STereoLithography ) is also known as Standard Tessellation Language or Standard Triangle Language. This file format is supported by many other software packages; it is widely used for rapid prototyping and computer-aided manufacturing (additive manufacturing or 3D printing). STL files describe only the surface geometry of a three dimensional object without any representation of color, texture or other common CAD model attributes. The STL format specifies both ASCII and binary representations. Binary files are more common, since they are more compact.
